One of the primary selling points of the IHG One Rewards program is its "No Blackout Dates" policy for Reward Nights. This means that as long as a standard room is available for sale at a participating hotel, you should theoretically be able to book it using your IHG points. This is a significant advantage over some other hotel loyalty programs that restrict point redemptions during holidays, major sporting events, or peak vacation seasons. However, it is important to understand the nuance: while there are no "blackout dates" in the traditional sense, IHG uses a dynamic pricing model for its points. This means the number of points required to book a room fluctuates based on demand, just like cash prices do. During a very busy weekend, a room might cost 80,000 points compared to 30,000 points on a quiet Tuesday. Furthermore, hotels only have to allocate a certain number of "standard rooms" for rewards; if all those specific rooms are booked, you might not see reward availability even if the hotel has "Executive" or "Suite" categories still open for cash. So, while you aren't blocked by the calendar, you are still subject to room availability and fluctuating "point costs."
